How to calculate integrals in matlab-matlab integral tutorial

php Xiaobian Zimo will show you how to perform integral operations in matlab. Matlab is a powerful mathematical calculation software that provides a wealth of mathematical functions and tools, making integral calculation simple and fast. By mastering some basic matlab integral functions and methods, we can help us solve various mathematical problems and deepen our understanding and mastery of mathematical knowledge. This tutorial will introduce in detail the basic methods and techniques of integrating in MATLAB to help you better use MATLAB for mathematical calculations.

1. First use the integral function int function, and then look at the function usage. In int(fx,x,m,n), fx is the function, x is the variable, m and n are the upper and lower limits, as shown in the figure below.

2. Enter syms x a in the command line window to define the symbolic variables x and a, as shown in the figure below.

3. Enter fx=a*x^2 and press Enter to define fx, as shown in the figure below.

4. Then enter int(fx,x,1,10) to calculate the integral, as shown in the figure below.

5. Finally, press the Enter key to see the integration result of the function in the range 1 to 10. If a is a constant, the result needs to be multiplied by the constant, as shown in the figure below.
